Definitions
- the present invention relates to a steering wheel turning angle detector for a vehicle to detect a steering wheel turning angle on the basis of the output of a steering wheel turning angle sensor attached to a steering wheel and a method for controlling yawing motion of the vehicle on the basis of the output of the steering wheel turning angle sensor.
- a steering wheel turning angle sensor attached to a steering wheel has a pulser for generating a single pulse at the neutral point of a steering wheel turning angle, predicts the neutral point of the steering wheel turning angle by the pulser, and resets a counted pulse value.
- the steering wheel turning angle sensor when the steering wheel turning angle sensor is attached to the steering wheel, the steering wheel turning angle is frequently displaced from the actual steering wheel turning angle. If there is no displacement upon attachment of the steering wheel turning angle sensor, the neutral point might be displaced due to any external force during the movement of the vehicle. If the neutral point is displaced in this manner, since the counted pulse value is reset upon reception of the neutral point pulse even if the neutral point pulse does not coincide with the neutral point of the actual steering wheel turning angle, the counted value does not indicate a suitable steering angle value.
- a steering wheel turning angle sensor attached to a steering wheel counts the pulses of a pulser provided in a steering column to measure a steering wheel turning angle, and the yawing motion of a vehicle is controlled with the detected steering wheel turning angle value.
- a steering wheel turning angle detector for a vehicle comprising a steering wheel turning angle sensor attached to a steering wheel to detect a steering wheel turning angle, yaw detecting means for detecting the yaw motion or yaw rate of the vehicle, steering wheel turning angle predicting means for predicting the steering wheel turning angle from the yawing state, and steering wheel turning angle correcting means for correcting the output value of the steering wheel turning angle sensor on the basis of an error between the output signals of the steering wheel turning angle sensor and the steering wheel turning angle predicting means.
- a steering wheel turning angle detector for a vehicle comprising a steering wheel turning angle sensor attached to a steering wheel to detect a steering wheel turning angle, wheel speed difference detecting means for detecting the difference of the left and right wheel speeds of the vehicle, steering wheel turning angle predicting means for predicting a steering wheel turning angle from the difference of the left and right wheel speeds, and steering wheel turning angle correcting means for correcting the output value of the steering wheel turning angle sensor on the basis of an error between the output signals of the steering wheel turning angle sensor and the steering wheel turning angle predicting means.
- the output of the steering wheel turning angle sensor is corrected by the steering wheel turning angle predicted from the yaw rate of the vehicle thereby to obtain a steering wheel turning angle near the actual steering wheel turning angle.
- the steering wheel turning angle can be predicted from the difference of the left and right wheel speeds, and the output of the steering wheel turning angle sensor is corrected by the predicted steering wheel turning angle.
- the steering wheel turning angle near the actual steering wheel turning angle can be obtained.
- a method for controlling yawing motion of a vehicle by controlling the yaw motion or yaw rate on the basis of the output of a steering wheel turning angle sensor attached to a steering wheel comprising the steps of predicting a steering wheel turning angle, and gradually correcting the output value of said steering wheel turning angle sensor on the basis of an error between the predicted steering wheel turning angle and the detected steering wheel turning angle of the steering wheel turning angle sensor for a predetermined period of time.
- the output of the steering wheel turning angle sensor is corrected by an error from the predicted steering wheel turning angle to obtain a steering wheel turning angle near the actual steering wheel turning angle, and it can be gradually corrected within a predetermined time, and hence the abrupt correction control of the yaw motion of the vehicle can be avoided.

- the output and hence the vehicle speed of the vehicle speed detecting means 13 and the steering wheel turning angle ⁇ ' obtained by the steering wheel turning angle detector 1 are input to reference yaw rate generating means 8, and the reference yaw rate obtained by the reference yaw rate generating means 8 and the yaw rate R obtained by the yawing detecting means 3 are input to subtractor 9.
- the subtractor 9 calculates the absolute value of the difference between the reference yaw rate and the yaw rate R. In other words, the displacement of the present yaw rate R from the predicted reference yaw rate is obtained.

- the timer Ts counts a time required to determine whether the vehicle is in the normal state or not, e.g., two seconds, and the timer Ts is reset whenever the steps S1 to S10 determine the state out of the normal range.
- the second step S2 first determines whether or not the vehicle speed V is equal to or higher than a lower limit speed, such as, for example, 8 km/hr, while the third step S3 determines whether or not the vehicle speed V is equal to or lower than an upper limit speed, such as, for example, 50 km/hr.
- a lower limit speed such as, for example, 8 km/hr
- an upper limit speed such as, for example, 50 km/hr.
- the fourth step S4 determines whether or not the yaw rate R of the vehicle is equal to or lower than an allowable yaw rate width, such as, for example, 5°/sec, and the fifth step S5 determines whether or not a traction control system is in operation, such as a decrease in the output of the engine, an application of brakes, for suppressing the excessive slip of a driving wheel.
- the sixth step S6 determines whether or not the steering angle S is within an allowable steering angle width.
- the allowable steering angle width is determined in response to the vehicle speed V is shown in FIG. 3, and the allowable steering angle width is set smaller as the vehicle speed becomes higher.
- the seventh step S7 and the eight step S8 determine whether or not the yaw rate R and the steering wheel turning angle S, this time, are equal to or lower than the previous mean yaw rate R A ' and the mean steering wheel turning angle S A ', the process advances to the eleventh step S11. This starts a correcting operation only when the vehicle is in a condition of more straight traveling than the mean yaw rate R A or the mean steering wheel turning angle S A (for example, when the steering wheel angle is straightening out) when the error of the steering wheel turning angle sensor 2 is corrected at the previous time, thereby obtaining a more accurate predicted steering wheel turning angle.
- the ninth step S9 determines whether or not the yaw rate R is in the normal range.

- the twenty-first step S21 sets the flag F
- a twenty-second step S22 resets the timer Ts, the Tc
- the twenty-third step S23 sets the mean yaw rate R A to R A ' and the mean steering wheel turning angle S A to S A '.
